Tutorial
When a member is logged in to your site, you can offer them the option of 1 Click Ordering shopping cart items. The site will use the information on file and immediately process the shopping cart item without them having to go through all the steps of putting in their information again.
BENEFIT: Make it as easy as possible for members to order and your site's revenues are likely to increase. Note: due to technical limitations, this is only available to sites using direct c.c. process and not through a 3rd party processor such as Paypal.
